BG Group announced Tuesday the conclusion of a drill stem test (DST) on the Guará Norte well (3-SPS-69) in Block BM-S-9 in the Santos Basin, offshore Brazil.
The DST confirmed high productivity of some 6 000 barrels of oil per day (bopd) of light oil (approx 30° API) with flow rates constrained by test facility capacity. Production potential from this well is estimated at around 50 000 bopd.
The results from the Guará Norte appraisal well are in line with those recorded from the DST on the original Guará well (1-SPS-55)* and reaffirm the excellent reservoir characteristics of this discovery.
The Guará Norte well was drilled at a water depth of 2 118 metres, approximately 305 kilometres (kms) off the coast of Sao Paulo state and around 15 kms northeast of the original discovery well.
BG Group has a 30% interest in the BM-S-9 concession, offshore Brazil (Petrobras, operator 45%, Repsol 25%).
